Dear All,
Recently we have migrated from exchange server 2010 to 2013,but still we have the 2010 servers as well in our environment,We have 3 exchange 2013 DAG members two in primary site and one in DR site.
for testing my DR site, i activated one of the mailbox database on the DR mailbox server ,which has a mailbox,i found something strange ,when i send a test email from my 2010 mailbox the DR mailbox is not able to receive the email at the same time if the email is sent from 2013 mailbox the DR mailbox is able to receive the email,even external email is not reaching the DR mailbox,what could be the issue?
